On my regionals this year, there was one question me and my partner couldn't answer. What is R phase of the cell life cycle?
They probably meant the R Point

On the double helix of the DNA ladder, which of the 3 major components of DNA make up the "steps" of the ladder?

Two of the four nitrogen bases (Adenine, Thymine, Cytosine, Guanine) joined together by weak hydrogen bonds form the "steps", if I'm correct.

Thank you! I looked this up online and couldn't find the answer anywhere.... I could only find sites that told me what made up the backbone and nucleotides.

No problem! Hate it when that happens... I got this off of a video on DNA replication. :-)

Does anyone have any idea on what the state test might include? I heard last year's contained a lot of genetic disorders and cell division. What are some things to watch out for?

Not sure, vennosah, but you're probably right.

Have you guys found any good sites for studying heredity? I've found a few. :?

Well, DNA from the Beginning is a pretty good website for the basics, and this one is useful for the ABO blood types. If you want something more in depth, I would suggest going to a library and getting some books on genetics/heredity. There also some very good YouTube videos on DNA structure/replication.

I'm pretty sure that the R-phase is the phase where the cell replicates DNA.

Also, am I the only one that thinks Heredity seems sort of easy?

EDIT: Nevermind, that's the S-phase.

It is pretty simple once you have all the DNA areas figured out. The only thing I had trouble with was pedigree analysis, but that can be mastered pretty easily with sufficient practice. I do hope it doesn't get too difficult at state though. :D
